pH MeasurementspH is the measurement of hydrogen ion concentration (H+) in water or soil. A pH of 7 is considered neutral. A pH below 7 is considered more acidic and a pH above 7 is considered more basic or alkaline. Water pH is important for plant management because it affects the solubility offertilizers and the effectiveness of insecticides and fungicides.

Below is a pH scale that ranges from 0 – 14 pH. Most plants have an optimal pH between 5.8 and 6.4 pH in soil-less media. For direct soil applications, a typical pH range of 6.5 – 7.0 pH is more common.

AlkalinityAlkalinity is another measurement growers should be aware of. Alkalinity is the ability of a substance to resist a change in pH. Alkalinity is generally defined as the buffering capacity of a solution.It affects how much acid is needed to control pH. Alkalinity is meas-ured in mg/L of Calcium Carbonate (CaCO3). The higher the alkalinity of your water, the more resistant it will be to controllingthe pH. The lower the alkalinity, the higher the volatility in achievingthe optimal pH value.

Common Alkalinity Problems and SuggestionsProblem Suggestion

High Alkalinity > 150 ppm

High media pH iron deficiency Acidify, Use acidic type fertilizer

Ideal greenhouse alkalinity: 60-120 ppm

Low Alkalinity < 40 ppm

Conductivity/TDS“EC” stands for Electrical Conductivity. Electrical conductivity is defined asthe ability of a substance to conduct an electrical current. Conductivity in asolution is directly proportional to the concentration of salts. Conductivityis temperature dependent and will rise in proportion to a temperature increase. As a result, it is important to consider an instrument that will automatically account for the temperature coefficient. Growers shouldconduct conductivity measurements to ensure the optimal level of nutrients are being delivered to their plants.

2 Scales for Measuring EC and TDSEC (Electrical Conductivity) is recorded in mS (milliSiemens) or μS (MicroSiemens). 1 mS = 1000 μS

TDS (Total Dissolved Solids) is a proportion of EC and is usually recordedin ppm (parts per million). Three common proportion multiplying factors,0.7 (hydroponics), 0.64 (soil science) and 0.5 are used to convert EC to TDS. Ex.: If the measured EC is 1000 μS, this can be converted bymultiplying it by 0.7 (hydroponics) which equals 700 ppm.

Sometimes, the EC of the fertilizer solution coming out of the hose is not what you expect. The problem can be caused by an incorrect dilution rate from the injector, either brokenor not properly adjusted, or the fertilizer stock concentration is wrong.

To check the fertilizer concentration, take a small amount from the stock solution, dilutethis in water to the target ratio, and check the EC. For example, if you think your injectoris set at 1:100, then put 10 mililiters into one liter of water (this will also give a 1:100 dilu-tion). If the EC of the solution is where it should be, then it is an injector problem. If theEC of the hand-diluted solution is off-target, then the stock concentration is not correct.

HI 993310DIRECT SOIL ACTIVITY AND SOLUTION CONDUCTIVITY KIT• Supplied with 2 probes for measurement versatlity


• Equipped with BEPS (Battery Error Prevention System)

HI 993310 is an instrument that has been specifically designed to address the need for conductivity measurementsin soil and liquids. It is supplied with two probes: HI 76305 witha stainless steel conical tip for direct soil measurement and HI 76304 for fertilizer enriched solutions.

HI 993310 measures both the soil conductivity in EC (mS/cm)as well as salt activity (g/L). The different scales can be selected through two keys on the front panel and two separateLEDs indicate which parameter is being tested. In addition, HI 993310 is equipped with an alarm LED that automaticallyturns on if the soil is too dry or nutritive substances such aspotassium or nitrogen are lacking. Demineralized water canbe added to the soil prior to proceeding with further tests.

Direct soil measurement is performed by HI 76305 stainlesssteel probe.

Why This Meter is So Important...Conductivity is an important factor in greenhouses and hydro-ponics and is measured in soil as well as in fertilizer solutions. Conductivity of soil is an excellent indication for the presenceof nutritive salts. Soil conductivity is checked before and afterfertilization to establish its effectiveness as well as ensuringthat the soil is not too saline or damaging to the plant roots. Conductivity of the irrigation water and fertilizer mixes arechecked to make sure values are within an acceptable rangeand a correct fertilizer concentration strength is being applied.

NPK


Plant NutritionThe three elements that are most neededby plants are nitrogen (N), phosphorous(P) and potassium (K). This is the reasonwhy they are called macronutrients andshould be given to plants.

Nitrogen is indispensable for the plant’slife and is a key factor in fertilization. Nitrogen allows the development of thevegetative activity of the plant, in particu-lar, causes lengthening of trunks andsprouts and increases the production offoliage and fruits. An excess of nitrogenweakens the plants’ structure creating anunbalanced relationship between theleaves and the stalks. In addition, theplant becomes less resistant to diseases.

Phosphorous is an important element inthe composition of DNA and RNA, the reg-ulators of the energetic exchange (ATP &ADP), as well as the reserve substances inseeds and bulbs. It contributes to the formation of buds, roots, blooming, andlignification.

A lack of phosphorous results in: stiflingof plant, slow growth, a reduction of production, smaller fruits and a lower expansion of the roots.

Even if Potassium is not a constituent ofimportant compounds, it plays a remark-able role in many physiological activitieslike the control of cellular turgor and the ac-cumulation of carbohydrates. It increasesthe size of fruits, their flavor, as well asyielding a positive effect on the color andfragrance of flowers. Potassium also makesplants more resistant to disease.

HI 83900SUCTION LYSIMETER FOR ROOT LEVEL SOIL MONITORING• Perfect companion to the HI 83200

• Monitor soil composition right at the roots

• Easy to use

The HI 83900 suction lysimeter is built with a porous ceramic cap connected to a transparent tubefor soil solution extraction. A rubber capillary is inserted in the tube passing through a rubber capand reaching the ceramic tip.

The HI 83900 series lysimeter is an ideal tool for collecting soil solution samples and then performquantitative chemical analysis. In this way the operator can easily monitor the level of nutrients,such as ammonia, nitrate, phosphorous and potassium, sulfate, calcium, magnesium.

The ceramic tip of the lysimeter can be used in all types of soil, and it is made of sinterized materialthat does not react with nutrient elements. The soil solution, therefore, is not affected by the chem-ical composition of the ceramic cap and the test results are always precise and reliable.

The HI 83900 allows the extraction of a solution from the soil by creating a vacuum (negative pressure or suction) inside the sampler tube, that exceeds the soil water tension. This will establish an hydraulic gradient for the solution to flow through the porous ceramiccap and into the lysimeter tube. Typically, a vacuum of about -60 cb (centibar) should be drawn.

For better monitoring of soil solution composition throughout an entire growth period of crops, atleast two lysimeters should be installed in the root zone of a representative plant—one at the upperpart and the other in the lower part of the root zone.

For better accuracy and repeatability of results, it is recommended to replicate the above describedinstallation in at least two more locations.

Dissolved Oxygen MetersDissolved Oxygen is a term commonly used for the measurement of the amount of free molecular oxygen (O2) dissolved in a unit volume of water usually expressed in milligrams perliter (mg/l), parts per million (ppm), or percent saturation. Dissolved Oxygen is an indicator ofwater quality.

In agriculture, growers should measure the dissolved oxygen if their primary water source isa natural body of water such as a stream, pond, or well. Low Dissolved Oxygen in irrigationwater encourages disease and poor growth.

Hydroponic growers should be measuring DO to ensure there is sufficient oxygen in their irrigation water that is being transferred to the roots of their plants.

The Quality of LightQuality of light is very important in the workplace, schools, greenhouses and public buildings.Too little light (or luminous intensity) affects the quantity and quality of performance of bothpeople and crops. HANNA's light meter uses special optic filters to match the spectral sensitivityof the human eye.

Luminous intensity is measured and reported in foot-candles (ft-c) or in lux (lx). Light metersare commonly referred to as lux meters. One lux is equal to one lumen per square meter and onefoot-candle is equal to one lumen per square foot. To convert measurements use the followingformula:

foot-candle = lux x 0.0929

lux = foot-candle x 10.764

HANNA's light measuring sensor is a photo diode that converts incident light into an electronicsignal that is read and displayed on the meters LCD as Klx which is 1,000 lx. So multiply the read-ing by 92.9 to get the measurement in foot candles.

Plant Light RequirementsLight provides the energy source needed for plants to manufacture food (photosynthesis). Theamount of light is commonly measured in foot-candles (ft-c) or lux. Plants differ greatly in theirlight intensity requirements. Indoor plants are often classified by the amount of light necessaryfor growth:

• Low (minimum 1.1 Klx, .8 to 2.1 preferred for good growth)• Medium (minimum 1.1 to 1.6 Klx, 2.1 to 5.4 preferred)• High (minimum 1.6 to 10.8 Klx, 5.4 to 10.8 preferred)• Very high (minimum 10.8 Klx, 10.8+ preferred)

About 1.1 Klx for 12 hours per day are necessary simply to maintain plant quality for one yearand at least 2.1 Klx for 12 hours per day are necessary for foliage plants to manifest any benefitfrom fertilization.

While lack of sufficient light results in poor plant growth, too much light can also be harmful.Shade plants cannot tolerate excessively high light levels. When a plant receives too much directlight, the leaves bleach or scald, sometimes dying. This often happens after moving a plant out-doors in direct light. Any changes in light intensity should be gradual.

What is Chlorine and ORP?Disinfection is a process of killing disease-causing organisms(or pathogens). Chlorine (Cl2) is a commonly used disinfec-tant because when mixed with pure water, it reacts toform hypochlorous acid (HOCl) and hydrochloric (HCl).HOCl (free active chlorine) is the most effective form ofchlorine for disinfection.

ORP stands for Oxidation Reduction Potential. OxidationReduction Potential is the potential at which oxidation occurs. In simple terms, ORP measurements allow for easymonitoring and tracking of critical disinfectant levels. Theideal ORP range for continuous disinfection is between650 and 700mV.

Chlorine Use in Irrigation waterChlorine can be an effective sanitizer in irrigation waterapplications. Some applications include:

• Recycling irrigation water

• Sanitizing irrigation water from natural sources such as ponds, rivers, streams or wells.

• Maintain and clean sprinkler and nozzle heads

• Clean up algae growing on walls, benches and soil surfaces

• Sanitizing produce

Calcium and sodium hypochlorite are widely used to con-trol waterborne pathogens and algae in irrigation water.We are most familiar with these materials as liquid bleach(sodium hypochlorite) and solid swimming pool “shock”(calcium hypochlorite)

HANNA Options for Measuring Chlorine and ORPHANNA has a long history of providing a wide range of instrumentation for measuring Chlorine and ORP. Theyrange from portable pH/ORP meters and Chlorine photometers, to in-line sanitation systems that combinethe continuous monitoring and controlling of chlorine concentration with the safe validation of ORP monitoring.

In some applications,ORP can be used to determine the effectsof soil compaction andthe viability of the soilto maintain the properlevel of oxygen.

ORPORP stands for oxidation reduction potential. ORP is a reading in millivoltsthat provides a measurement of thesample’s ability to oxidize (or sanitize)contaminants. Water ionizers are in-tended to raise the alkalinity of your tapwater to counteract the in-take of acids.The water sample should show a nega-tive ORP value after the ionizationprocess has been applied to your water.

ORP Preparation and Measurement1) Remove the protective cap. Visible

residue from salt deposits is common. Rinse off any deposits with water.

2) For faster response times, treat the ORP platinum (metal) surface prior to use by soaking it in pre-treatment solution for 15 minutes. Generally useHI 7092M Oxidizing pre-treatment solution when planning on measuring+mV ORP readings. If you are planningon measuring -mV ORP readings, use HI 7091M reducing pre-treatmentsolution.

3) If pre-treatment is not performed, the electrode will take significantly longer time to respond. Additionally, the recently pre-treated electrode (metal) surface will dissolve off over time so it will have to be restored by future pre-treatments.

4) To measure ORP, immerse the tip of the tester in the sample, stir gently and wait for the reading to stabilize.

HANNA,a world leader in EC and pH control technology has worked with leading growers to developadvanced system solutions for crops of any type. The HANNA Fertigation System provides precisecontrol of pH and fertilizer injection. Unlike flow driven systems of the past, the HANNA Fertigation System constantly measures the actual EC and pH of the water, allowing the system toadd the precise concentration of fertilizer directly to the irrigation supply. The HANNA System is abypass system which does not limit line flow or pressure. This allows the user to accurately inject fertilizer from 5 GPM up to 300 GPM.

The HI 8000 series controller included with the system has 10 programs that allow the user to setvarious EC and pH values for a variety of plants. Each system allows the injection and mixing of upto 4 fertilizers. If preferred, each fertilizer injector can be set to a specific percent, allowing the userto mix combination fertilizers from basic N - P - K elements, providing a considerable cost savings.The HANNA Fertigation System also controls up to 32 irrigation valves for complete automation ofthe fertigation process.

Pro’s ChoiceHANNA’s Fertigation and pH Control Systemscan be found in a number of notable green-houses throughout the USA: Van WingerdenGreenhouses NJ, Gro-Rite NJ, Van Vugt NJ,Michael’s Greenhouse CT. Additional installa-tions include such greenhouse leaders such asOVW Greenhouse NJ, and De Groot GreenhouseNJ, Van Wingerden Greenhouses WA.

Quality and ServiceThe HANNA systems are above all reliable,durable and require little to no maintenanceand each unit is backed by impeccable trainingand support …just ask our clients!

“We replaced our manual injectors with theHANNA system and are now adding supplemen-tal fertilizers to optimize the nutrients to theplants.

The result is healthier plants and longer shelflife when delivered to our customers”.

Don’t Let Your Electrode Dry OutIdeally, pH electrodes should be stored in a storage solution when not inuse. Placing the electrode in a small glass filled with storage solution issuitable. An option for pocket meters is to place a small piece of spongeinto the meter’s cap and pouring storage solution into the cap to wet thesponge. Pouring out the excess solution beforehand, the cap can then beplaced on the meter.

If a storage solution is not available the next best option is to use pH 4.01buffer (pH 7.01 is also suitable to a lesser extent).

Clean Your Electrodes Before UseClean the liquid junction of your electrodes once a day or at least once aweek to prevent junction clogging and to maintain accuracy. Immerse theelectrode in the proper cleaning solution for at least 15-20 minutes.

HANNA offers a wide range of cleaning solutions, for general purpose andspecific applications.

Replace Your Electrode Once a Year, Solutions Once a MonthIf your electrode takes too long to stabilize a reading or readings fluctuatewildly, it is probably time to replace the electrode. 6 months to 1.5 yearsis the typical life span of any pH electrode.

Change your solutions once a month to avoid erroneous calibrations ormeasurements due to age or contamination. Opening a new HANNA sachet guarantees freshness every time.

Solution that is Fresh Every TimeHANNA single-use sachets are a great wayto ensure a fresh solution is used everytime you calibrate. Just tear open thepacket and insert the electrode. Theselight-tight sachets are also ideal fortesters—they fit right in!
